Abstract: The present invention relates to an ink composition suitable for being ejected from an inkjet marking device at an operating temperature. The ink composition comprises stable dispersed colorant particles and stable dispersed latex resin particles, wherein the ion sensitivity of the colorant particles is larger than the ion sensitivity of the latex resin particles, the ion sensitivity of the colorant particles (ISc) being expressed according to equation 1, and the ion sensitivity of the latex resin particles (ISl) being expressed according to equation 2: ISc=Zcav(xcM NaCl)/Zcav(H2O)  equation 1 ISl=Zlav(xl M NaCl)/Zlav(H2O)  equation 2 The invention further relates to an ink set comprising such an ink composition and a primer composition comprising a precipitating agent, preferably a multivalent metal salt. The invention also relates to a method of printing using such an ink set. The inks and ink sets according to the present invention are capable of improving the transport robustness of prints, in particular of prints on machine coated media.
